WOODWORKlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 608,072, dated July 26, 1898.

, Application filed September 2,' 1897. Serial No. 650,3'71- (No model.)

To all whom it may concern: 1

Be it known that I, CHARLES FRANK Ovnn- MYER, of Fostoria,in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Woodworking- Maehines; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in woodworking-machines, the primary object of the same being to provide a machine for cutting the dadoes or transverse grooves in strips which are used in the manufacture of top frames for vehicles. The particularconstruction and arrangement of theparts also adapts the machine for making balusters and doing any kind of square turning.

IVith the above objects in view the invention consists in a machine comprising certain details of construction, including the particular combination of parts, all as fully described in the following specification and more particularly set forth in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a woodworking -machine constructed in accordance with my invention. Fig. 2 is a plan View of the machine. Fig. 3 is a transverse sectional view.

The supporting-frame of the machine is made up to present the longitudinal top beams 1 1, which are supported upon the legs or uprights 2, the said legs being thoroughly braced, as shown, and connected at their upper ends by the cross-pieces 3. At the ends of the frame are mounted bearings for a 1011- gitudinal shaft 4, upon which the cutters are mounted, one end of said shaft being extended beyond the supporting-frame, where it is provided with a pulley 5, over which the driving-belt passes. Upon the supportingframe is adj ustably mounted a table consisting of longitudinal beams 6 6, which are connected to each other at their ends and centrally by the cross-bars 7. This table rests upon hand screws 8, which pass upward through the longitudinal beams of the frame, engaging threaded sockets therein to adjust the said table vertically, and in order to hold the adjustment the table is provided with depending plates 9, having slots 10 therein, through which passes a bolt or set-screw 11 into the suppmrting-frame. At the ends of the adjustable table are secured plates 12, upon which rest the bearings for the cutter head shaft.

The work-holder, upon which the work is placed and fed to the cutting-knives, consists of the longitudinal side pieces 29, which are connected to each other by the cross-pieces 30, said cross-pieces being adjustable and held by the longitudinal strips 31, which lie within the side pieces and adjoining the same. The end cross-pieces 32 of the workholder are provided with slots 33 near one end, and through these slots pass bolts 34,

which secure a guide-rail 35 upon the workholder, said rail being curved longitudinally, as shown; but others can be substituted therefor when desired. In cutting strips to be used in the manufacture of tops for vehicles they are placed against the guide-rail and held in place thereon by levers 36, which are in sliding engagement with slotted plates 37, let into cross-pieces of the work-holder, the levers be ing jointed and connected to each other by a rail 38,'forming the operating-handle or hand-rail. This work-holder is placed upon the vertically-adjustable table and is adapted to be moved thereon to properly bring the strips or material to be cut in contact with the cutters. From the foregoing description, in connection with the accompanying drawings, it will be apparent that a machine constructed in accordance with my invention provides one in which the strips to be used in the manufacture of tops for vehicles can be readily cut or provided with the dadoes by which the said strips are interlocked in forming the frame or top. It is also obvious that other work could be accomplished upon the machine. For instance, the knives could be arranged to cut balusters of ornamental appearance and angular in cross-section.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- rying cutters, an adjustable table, and a workholder mounted to slide thereon, in comb1nation with a series of clamping levers con- 1 1. In a woodworking-machine, a shaft carnected to a hand-rail having any desired curve to conform to the lateral contour of the work to be clamped, said levers being adjustable on the Work-holder to suit the curvature of the hand-rail, substantially as described.

2. In a woodworking-machine, a shaft carrying cutters, an adjustable table, and a Workholder mounted to slide thereon, in combination with a series of clamping-levers connected to a hand-rail having any desired curve to conform to the lateral contour of the work to be clamped, said levers being adjustable on the work-holder to suit the curvature of the hand-rail, and means providing for the individual lateral adjustment of said levers in a line of any desired curvature, substantially as described.

3. In a woodworking-machine, a shaft carrying cutters, an adjustable table, and a Workholder mounted to slide thereon, in combination with a series of L-shaped clamping-levers connected to a hand-rail having any desired curve to conform to the lateral contour of the work to be clamped, said levers being adjustable on the work-holder to suit the curvature of the hand-rail, substantially as described.

4. In a Woodworking-machine, a shaft carrying cutters, an adjustable table, and aworkholder mounted to slide thereon, in combination with a series of clamping-levers connected to a hand-rail having any desiredcurve to conform to the lateral contour of the Work to be clamped, slotted plates mounted on the cross-pieces of the frame of the Work-holder to receive and permit the lateral individual adjustment of the clamping-levers to suit the curvature of the hand-rail, substantially as described.

5. In a Woodworking-machine, a shaft carrying cutters, an adjustable table, and a workholder mounted to slide thereon, in combination with a guide-rail secured at a point intermediate its ends and having its ends held by fasteners, and a series of clamping-levers connected to a hand-rail having a curvature corresponding to that of the guide-rail, said levers being adjustable on the Work-holder to suit the curvature of the hand and guide rails, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
